Setting Permission Requests while registering a new app: the app can still access and update user profile / settings / friends and post new activities and measurements without checking the Permission Requests for Health Information.
Unique Application Name and Estimated Date of Publication is required.
Once your Application is registered, click on 'Application Keys and URLs' for Client ID and Client Secret.
Run the InitializeOAuth Choreo, specifying the Client ID and Client Secret from the app you registered at RunKeeper. The InitializeOAuth Choreo will return an authorization URL and a callback ID (required for the FinalizeOAuth step).
Open a new web browser, navigate to the authorization URL returned by the InitializeOAuth Choreo, and click "allow" to grant the app access to your RunKeeper account.
Run the FinalizeOAuth Choreo, specifying the callback ID returned earlier by the InitializeOAuth Choreo, to obtain an OAuth access token that can be used to access the RunKeeper API.
